Be it known that I. WILLiAM H. SHEASBY, a citizen oi the United States of Boner-ice and,

a resident of Los Angeles, in the county of verse section on the line 2 2 of Fig. J and Fig. 3 u )erspective View of the closure-plug detached The object of this invention is to adapt the journal-box for use more purticultulv vith sjournul of the type wherein is en'iploycd a cir-- culur series of untilriction loam-sustaining simple, strong, and eliicieut closure plug or cup for the outer end of the box.

Referring to the (lrews'iugs by reference characters, A designates the ieurnzi-l of :1 curaxle of the usual coustruci i hzivn vvl to it by :1- key II? :1 raring-slot, :e ti ts sl w (I being providei'l tii mien end of its bearing-sitrwith a radial t 'tttflwil" on whirl; adapted to run Ltitlli pacing rollers F, Whose ends a Q 1 j, Where the rollers the reels and are held in place on the tracks by the eose rings intermediate these spaeinq-rollers are the loudsustaining rollers E, which support the cylindrical outer member or box D. I no claim to the foregoing construction, it is shown and descr'ieti in the patent granted to Green, Lyons, and Garey, numbered 802,362, dated C ctober 17, 1905,

Longitudinal groov 3 a are formed in the oxle-spindle near the outer thereof at diametrically opposite points, and registering; holes I) are formed in the sleeve B, whereby it suitable tool may be inserted said grooves {I and engaged into holes 3)" for the 4,, the sleeve oil' the spindle when becomes worn. The grooves a are covered by the sleeves except Where the holes i)" register with the grooves ut the inner ends rt is to provide :1

l I g l l l confined in e cenirelrecess of the grooves. The ends of the grooves e are covered by u ring-piste C, removahly Se cured to the end of the spindle by means of leg-bolts c. This ring- C overlaps the end of the sleeve B and serves to assist in holding it v on the spindle.

plug a is driven into a tapered A pin. or hole formed in the center of the end of the axle. The head of this pin transmits the end thrust of the axle to a freely-rotatable hell I,

h in the cylindrical plug ii of the journal-box. This ball is loosely confined in said recess by a ring-lil e plate J, secured to the inner face of the plug,

and the ball at a point opposite its bearingpoint on the plug a bears against a wearplate K, set in recess in the bottom of the recess 71". in this manner the bell i loosely retained in the 2117 and free to rotate in all. directions, whereby the end thrust of the axle will be taken up with the least possible fric- 7 tion and wear. A central zixiulpessrige 71 is formed in the cup suitable tool for the removal of the Wear-- plute I; when it is necessary to renew the same.

in e rubbet or :zunulsr re d, formed in infirm is'iitted e (tibis put 1, which is ield rig lilSt rotation by means of ,i ti, "ustened in the end of the box and partly into the packing-ring This packingring hears upon the face of the spindle and prevents the ci'itruuce of dust to the box, and it held in place by an annular ringm, Whose pe ipheral wlge engages over an annular flange on the exterior of the be); The closure plug or cap It is formed cylindrical in shape and is of diameter to nicely 'iit Within the outWa-rdl -pr0jecting end of the box. The inner en. of this cylinder is closed by a head, from the center of which a boss outdly projects to provide the metal necessary for the ball-r tuining recess 7t, and the outer end of this boss is shaped into a nut 7i, whose outer surface is flush with the end of the box and which is adapted to receives *rench i or the removal of the plug from the box, he piug'is held in the end of the box by means of twoseries of radial peripheral to permit the insertion of iiprtuecting' flanges 72,, formed on the surface of the plug" at diametrically opposite sides of the same, each flange extending .quarterway around .the periphery of the plug. These segmental flanges are adapted to interlock with. a series of similarly shaped and disposed flanges 0 formed on the interior of the box.

To insert the plug, it is simply necessary to adjust it axially, so'that its flanges 7t shall come opposite the diametrically opposite spaces between the box-flanges d, then insert the plug into the box, and then give it a quarter-turn in order to interlock the flanges 7t with the flanges d, as shown in Fig. 1. To look the plug in its closed position, 1 tap through the box a set-screw (1 which engages the outer'iace of one of the flanges It. An annular flange d is iorn'ied on the interior Wall of the box in such position that the inner end of the closure-plug will abut against it when the plug is slid in to a point where its flanges will engage the lock-flanges on the box. An annular redial flange h is formed on the outer end of the plug and is adapted to fit within and be flush with the outer end o1 the box when the plug is'inserted and locked, this flange serving, therefore, to cover the end of the recesses or spaces between the ends of the segmental lock-flanges.

The above-described closure-plug" simple in constructirni, easy to insert and to reunite, effectually excliules all dust when closed, and ailords a rigid support for the end-thrust ball i.

Upon the upper surface of the box is formed a hemispherical boss N, -which. is adapted to receive the bearing-block O of the truck-frame, the under side of this block be- .ing provided with a hemispherical socket which nicely and freely works upon the bossN. The ODJGCh oi this construction is to afford a universal pivotal connection between whet itiairn, and desire to secure by Letters Patent, is

1. in combination with an axle structure and a journal-box inelosing the same and having a projecting: cylindrical end portion, there being an annular interior stop-flange d in this projecting portion of the box, and a series of inwardly-projecting separated segmental flanges on the interior of this projecting portion between said stop-flange and the outer end of the box, and a closure-plug cylindrical in shape and provided. with a series of separated segmental outwardly eXtending flanges on. its outer surface and an annular radial flange FL on its outer end adapted. to fit within the outer end of the box, and a locking device for this closure-plug 2. In combination with an axle structure and a cylindrical box inclosing the same, a closure-plug in the outer end of this box provided with a central rccessh, a ball confined in this recess, a wear-plate K. at the bottom of this recess to-receive the end thrust of the ball, said closure-plug being provided with a 3. In combination. with a journal -b0X having: formed in its outer end a series of inwardly-projecting separated. segmental flanges, a closure-plug cylindrical in shape adapted to within the end of the box and provided. with two series of outwardly-pr jeeting separated. radial flanges adapted to fit between and interlock with the flanges on the box, and a locking" device for this plug.

4. cmnhination with a journahbox having form ed. in i on ter end opposite inwardly pro ecting segmental flanges and an inwardlyproiectin flange inside of said .langros, a closure-plug carrying an endthrust element in its inner end or face and provided periphe illy with outwardly-projecting segmental. tian said plug being" adapted. to iit within the outer end of the journahbox, ti locking device for plug, and an axle having its spindle portion journaled in thebox and its outer end engaging said ei'ichthrust element.

in testimony whereof i hereunto eiiix my signaturenn the presence of two witnesses,this 14th day of December, 1906.
